Fig. 1 is a schematic block diagram of an air conditioner according to an embodiment of the present invention. Fig. 2 is a schematic front view of an indoor unit of an air conditioner according to an embodiment of the present invention. Fig. 3 is a schematic plan view of the indoor unit of the air conditioner of the embodiment shown in fig. 2. Fig. 4 is a schematic cross-sectional view taken along a section line a-a in fig. 2. As shown in fig. 1 to 4, the air conditioner 100 of the present embodiment includes an air conditioner indoor unit 110 and an air conditioner outdoor unit 120. The air conditioner indoor unit 110 and the air conditioner outdoor unit 120 operate in an effective cooperation manner to complete the refrigeration and heating cycle of the air conditioner, thereby realizing the cold and hot adjustment of the indoor temperature. The indoor unit 110 of the air conditioner of the present embodiment includes a cabinet 10, an evaporator 40, a cross-flow fan, a grill 20, and a plurality of auxiliary intake fans 30. The casing 10 includes a skeleton (not shown) for supporting the cross flow fan and the evaporator 40, and a housing covering the skeleton. The front side of the housing forms the front panel of the indoor unit 110 of the air conditioner, the air inlet 101 is arranged at the top of the casing 10, and the bottom of the casing 10 is provided with the air outlet 102.
The evaporator 40 exchanges heat with air flowing therethrough to change the temperature of the air flowing therethrough. The cross-flow fan causes the ambient air entering from the air inlet 101 to flow to the evaporator 40, and causes the heat-exchanged air after heat exchange by the evaporator 40 to flow toward the air outlet 102, so as to be exhausted to the working environment of the indoor unit 110 of the air conditioner.
The evaporator 40 is part of a refrigeration system, which may be implemented using a compression refrigeration cycle that uses a refrigerant compressor, a condenser, the evaporator 40, and a throttle device to implement heat transfer. The refrigeration system consists of a refrigerant and four major components, namely a compressor, a condenser, an expansion valve, and an evaporator 40.
The refrigeration system causes the evaporator 40 to release refrigeration through a refrigerant compression cycle. The refrigeration system generally has four major components, namely a compressor, a condenser, a throttling device and an evaporator 40. The working principle is as follows: the compressor is used as the power of the refrigeration cycle, is dragged by the motor to rotate ceaselessly, extracts the steam in the evaporator 40, and improves the pressure and the temperature of the refrigerant steam through the compression action, thereby creating the condition that the refrigerant steam and the heat are transferred to the external environment medium, namely compressing the low-temperature and low-pressure refrigerant steam to a high-temperature and high-pressure state.
The condenser is a heat exchange device, and takes away heat of high-temperature and high-pressure refrigeration steam from the compressor by utilizing an environment cooling refrigerant, so that the high-temperature and high-pressure refrigeration steam is cooled and condensed into high-pressure and normal-temperature refrigeration liquid. When the air conditioner is in the cooling mode, the heat exchanger in the outdoor unit 120 is a condenser. When the air conditioner is in the heating mode, the heat exchanger in the indoor unit 110 of the air conditioner is the evaporator 40.
The refrigerant liquid at high temperature and normal temperature passes through the throttling element to obtain low-temperature and low-pressure refrigerant, and then is sent into the evaporator 40 for heat absorption and evaporation. The temperature of the refrigerant liquid can be lowered by lowering the pressure of the refrigerant liquid according to the principle of correspondence between the saturation pressure and the saturation temperature.
The evaporator 40 serves as another heat exchange device, and the throttled low-temperature and low-pressure refrigerant liquid is evaporated (boiled) in the evaporator to become steam, so that ambient heat is absorbed, the ambient temperature is reduced, and the purpose of refrigeration is achieved. The evaporator 40 is of three-stage type. The evaporator 40 is provided in three stages to semi-surround the cross flow fan 50, so that the air flows formed by the evaporator 40 and the cross flow fan 50 can be fully contacted, thereby improving the heat exchange efficiency.
A plurality of auxiliary intake fans 30 are embedded in the intake grill 20 to introduce air into the casing 10 to assist the cross-flow fan 50 in generating an air flow from the intake opening 101 toward the evaporator 40. The auxiliary air intake fan 30 may be a centrifugal fan, an axial flow fan, a diagonal flow fan, or the like. The auxiliary intake fan 30 is disposed at the air inlet 101 of the indoor unit 110 of the air conditioner, and when the auxiliary intake fan 30 is activated, the auxiliary intake fan drives the ambient air to form an airflow flowing into the casing 10. The cross flow fan provided in the casing 10 promotes the ambient air introduced from the inlet 101 to flow toward the evaporator 40 during the cooling and heating processes of the air conditioner. The air flow formed by the auxiliary intake fan 30 is mixed with the intake air flow formed by the cross flow fan to increase the intake rate of the indoor unit 110 of the air conditioner.
The indoor unit 110 of the air conditioner of the present embodiment includes a cabinet 10, an intake grill 20, and a plurality of auxiliary intake fans 30. The housing 10 is provided with an air inlet 101. The evaporator 40 and the cross flow fan 50 are provided inside the cabinet 10.

The plurality of auxiliary intake fans 30 may be the same type of fan. The plurality of auxiliary intake fans 30 may be turned on and off simultaneously when the air conditioner indoor unit 110 is in operation. The auxiliary air intake fans 30 are sequentially arranged along the transverse direction of the casing 10, and the arrangement positions are uniformly distributed at the air inlet 101, so that air intake is more uniform. During the operation of the indoor unit 110 of the air conditioner, the auxiliary air intake fans 30 can guide air into the casing 10 simultaneously, so that air intake is more uniform.
The number of the auxiliary air intake fans 30 is two. A plurality of auxiliary fans are disposed in the middle of the air inlet 101. The number of the auxiliary air inlet fans 30 is two, so that the air inlet requirement of the air conditioner indoor unit 110 is met, meanwhile, the energy consumption is reduced, and a better effect is achieved by using less energy.
